Domain 1: Care Continuum (Questions 1–50)
1. A patient is diagnosed with Hodgkin lymphoma. The nurse
understands that this malignancy is characterized by the presence
of which type of cells?
A) Reed-Sternberg cells
B) Auer rods
C) Lewy bodies
D) Negri bodies
Answer A: Reed-Sternberg cells
,Rationale: Reed-Sternberg cells are large, binucleated or
multinucleated lymphocytes with prominent nucleoli, often described
as "owl-eyed," and are the hallmark of Hodgkin lymphoma.
2. A patient with a BRCA1 gene mutation is at increased risk for
which malignancies?
A) Lung and colon cancer
B) Breast and ovarian cancer
C) Pancreatic and gastric cancer
D) Prostate and testicular cancer
Answer B: Breast and ovarian cancer
Rationale: BRCA1 and BRCA2 mutations are associated with
significantly increased risks for breast and ovarian cancers.
3. A nurse is providing education about cancer screening. According
to the American Cancer Society, which screening recommendation
is appropriate for a 55-year-old male with average risk?
A) Annual PSA screening beginning at age 50
B) Colorectal cancer screening beginning at age 45
,C) Annual chest X-ray for lung cancer
D) Routine digital rectal exam annually
Answer B: Colorectal cancer screening beginning at age 45
Rationale: The American Cancer Society recommends colorectal

C) Administer prophylactic antibiotics
D) Restrict visitors completely

completing treatment. Which intervention should the nurse
recommend?
A) Complete bed rest
B) Graduated exercise program and energy conservation strategies
C) High-dose vitamin supplements
D) Restrict all physical activity
Answer B: Graduated exercise program and energy conservation
strategies
Rationale: Graduated exercise and energy conservation are evidence-
based interventions for cancer-related fatigue.
6. A patient with advanced cancer is experiencing dyspnea. Which
non-pharmacologic intervention is most appropriate?
A) Encourage supine positioning
B) Position the patient in high Fowler's with a fan circulating air
C) Restrict fluids
